The UV Minder® Model 3D UV intensity meter is capable of measuring the
UVA and UVB spectra. The UV meter shows the intensity of UVB (also called
SUV – Sunburning UV) in Minimal Erythemal Doses per Hour (MED/Hr), the
accepted clinical measure for sunburn potential.
The UVA detector measures UV intensity in the range between 320 and 400
nm, displaying UVA irradiance in milliwatts per square centimeter.
Also available as the UV Minder® Model 3D-XP Xeroderma Erythemal UV
Intensity Meter for measuring very low UV intensity to 3 decimal places. Please
specify wavelength range required when ordering. The UV meter is very easy
to use with its sensors mounted on the meter, making UV measurement easy,
and its light weight makes it very easy to handle. The UV Minder UV meter is
a very versatile instrument.
The UVA and SUV sensors are conveniently mounted on the top of the meter,
making it easy to point the sensor at the target and register the result by
selecting the desired sensor. A green ﬂashing indicator light on the keypad
shows which sensor is active. Press the HOLD button to freeze the current
reading. To release, press the HOLD button again. Turning off the meter also
resets the hold status. The HOLD function is useful if the detector needs
to be in a place where the display can not be read. Once the detector is in
place press the HOLD button. You can now move the detector and meter to a
position where you can read the display.
An analog output is provided at the bottom of the meter. This allows the
user to continuously monitor and record the intensity irradiated on the active
detector. Recording can be accomplished by a strip chart recorder or an A/D
card connected to a computer. Plug the supplied 0.141 inch phone plug into
the analog output jack. The red lead is positive and the black lead is negative.
The calibration factor for the analog output is 0.1[Volt/(MED/HR)] or 0.1[Volt/
(mW/cm2)].
